It is important to have asymmetry in a solar cell because:

Question

Answer

the asymmetry improves the efficiency of the cell by reducing reflectivity at the surface

Answer

the asymmetry encourages flows of electrons from the p-type material to the n-type material, setting up voltage and current

Answer

without the asymmetry, electrons cannot accept an incoming photon

Answer

the asymmetry encourages flows of electrons from the n-type material to the p-type material, setting up voltage and current
